Antwort auf Beitrag Nr.: 66.397.694 von Tirolesi am 12.01.21 12:44:24Es ist gelinde gesagt schon übel, dass man als Unternehmen auf so einen Bullshit, der von irgend einem Nicht- bzw. Halbwissenden da einfach mal so hingerotzt wird, antworten/eingehen muss.
Aber in der Phase vor Lizenzerteilung absolut professionelle und umgehende Antwort 👍

Antwort auf Beitrag Nr.: 66.386.621 von Tirolesi am 11.01.21 18:05:54Hi ....
The Greenland media queried us on the article.
Our response is below:
We note the comments from Anton Chakhmouradian.
“Greenlanders should take the company’s claims about the abundance of the strategic rare earth minerals in Kuannersuit and their ability to extract them with a grain of salt.”
While it is appreciated that Professor Chakhmourandian may have technical knowledge of rare earth minerals and a basic understanding of processing, his comments reflect a cursory glance at the Kvanefjeld Project, and not a deep knowledge of the geology, and the rigorous studies that have developed the metallurgical methods designed to process the ores. Nor is there any reference to development plans and the associated impact assessments.
Regarding abundance, or mineral resource estimations.
Mineral resources for the Kvanefjeld Project have been estimated following the Australian Joint Ore Reserves Committee (JORC) reporting code, that applies rigorous constraints. While Greenland Minerals conducted the extensive drilling programs, the mineral resources were independently calculated by industry specialist consultants SRK, that conducted a full audit of the sampling protocols, the transport of samples to accredited laboratories, and a detailed evaluation of the precision and accuracy of the geochemical analyses. Mineral resource estimates have been established across three zones, with the most detailed, or highest density of drilling being conducted at the Kvanefjeld deposit. This allows for SRK to qualify part of the resources in the ‘measured’ category, which is the highest confidence category under the JORC code. Incorporating the outcomes of engineering and feasibility studies, part of the resources are converted to ‘ore reserves’, which then take into account economic considerations.
In addition to the mineral resources and ore reserves having been independently estimated by a leading international consultancy (SRK Consulting), an additional audit/evaluation was conducted by another specialist consultancy on behalf of the Greenland Government (this reflects requirements of Greenland’s Mineral Resources Act). This was undertaken by Auralia Mining Consultants. Auralia confirmed that the resource estimation of 16 oxides and 1 metal have been completed to JORC standards (see ASX company announcement of 28 April, 2020).
Variability of ore mineralogy and chemistry
The processing of rare earth ores requires a detailed understanding of the minerals that make up the ore, including the value minerals (i.e. steenstrupine) and non-value minerals (mostly silicate minerals such as amphibole and feldspar). Greenland Minerals has been conducting detailed mineralogical studies over many years, in parallel to detailed geochemical studies that investigate variability within established ore-bodies. This allows zones to be clearly mapped in three dimensions that are characterized by subtly different mineralogical characteristics. During metallurgical investigations, the performance (i.e. rare earth recoveries) are evaluated in these different zones. Ore reserves are characterized by specific, near-surface zones of consistent mineralogy. In general, the metallurgical performance of most of the defined zones is consistent. SRK consulting published a brief paper on the methodology that was developed to geochemically map the different ore zones within the lujavrites at Kvanefjeld.
Mineralogical studies and steenstrupine investigations
Detailed mineralogical studies on the Kvanefjeld ore and the specific ore minerals have been conducted through a number of research programs; the main ones being a Post-Doctoral research study on Kvanefjeld mineralogy undertaken at the University of British Columbia in 2011-2013, and a detailed QEMSCAN quantitative mineralogical study by SGS Oretest in Perth in 2013-2015. Additional studies have been conducted at the CSIRO in Australia.
Process development and metallurgical studies
Since 2009, detailed metallurgical studies have been conducted that have developed the processing methodology for Kvanefjeld. Early in the investigations, flotation was identified as being the most effective means of beneficiating the ore, a process whereby key value minerals are concentrated for further treatment to extract and recover saleable products.
In 2011 and 2012 approximately 270 batch flotation tests were performed by global western world experts in froth flotation using commercially available reagents. This testwork revealed the use of hydroximate flotation collector chemistry as being the most effective.
The first beneficiation pilot plant was performed in August 2011 to process a bulk concentrate for refinery testwork and examine the larger scale flotation performance. A total of 1300 kg of ore was treated at a rate of 100 kg/hour.
Further optimisation work and equipment design work was completed in 2012 culminating in the operation of a second flotation pilot plant campaign in November 2012. During this pilot plant a total of 4000 kg of ore was treated at 150 kg/hour.
A third flotation pilot plant was performed in May 2015 at GTK Laboratories in Finland. This pilot plant was successful in treating 26 tonnes of ore producing 2 tonnes of mineral concentrate. The mineral concentrate was subsequently treated in a refinery pilot plant in September 2015 at Pori Finland with a scale up ratio of 1500:1 to the expected commercial operations.
Refinery testwork has focussed on acid leaching of the mineral concentrate produced via flotation. A variety of concentrates have been produced from a range of ore types to ensure the refinery metallurgy is valid across the ore body.
The refinery metallurgical program commenced in 2010 with extensive bench scale leach programs to examine pressure leaching and atmospheric leaching. Atmospheric sulphuric acid leaching was selected in 2012 as the best leaching option due to simplicity and high value extractions. The rest of the refinery testwork was focussed on this method and treatment of the downstream leach solutions/residues.
Over 100 bench scale leach tests, solvent extractions tests and solid liquid separation observations have been made using the atmospheric leach and solvent extraction process. These tests were performed during 2011 though 2015. The information from these tests was used to develop and optimise the refinery metallurgical flowsheet which was used as the design for the 2012 PFS, 2015 Feasibility Study and 2016 Feasibility Study Update.
GML completed continuous leach testwork in 2014 over a 100 hour period. This work was performed to examine the continuous behavior of the leach and generate samples for solid liquid separation. Information from this testwork was used to inform conditions and reduce risk for the refinery pilot plant campaign.
In October 2015 GML performed a pilot plant campaign on the refinery flowsheet at Outotec’s Research Facility in Pori, Finland. This pilot plant was operated continuously for 250 hours treating approximately 250 kgs of Rare Earth mineral concentrate from Kvanefjeld. Approximately 25 kg of high-purity mixed rare earth carbonate was produced as the final product of the campaign.
The project scope and terms-of-reference for the Kvanefjeld Project development strategy were established with extensive stakeholder input. The Greenland Government requested that two processing stages were conducted in Greenland, to ensure Greenland stood to benefit from the project sufficiently, rather that most processing taking place off-shore. The two stages include the beneficiation and refining stages.
Involvement of Rare Earth Industry specialists Shenghe Resources
In 2016, Greenland Minerals commenced a strategic relationship with Shenghe Resources Holding Co., one of the leading rare earth companies globally in terms of technical expertise, and being a large-scale international supplier of high-purity rare earth metals and oxides.
Shenghe was commencing an international strategy to work collaboratively with companies outside China to establish new international rare earth supply chains. Shenghe have provided technical consultancy services to numerous western rare earth companies, and therefore have a strong understanding of many of the advanced rare earth projects in terms of geology and metallurgy. As Shenghe’s Chairman Mr Hu Zesong explained in his presentation to the Confederation of Danish Industry conference in December 2019, Shenghe had investigated over 50 rare earth projects outside China, and following detailed investigations and due diligence, Shenghe selected Kvanefjeld as the strongest project with the greatest potential. It is important to appreciate Shenghe has some of the best technicians in the rare earth industry globally. Shenghe have recently played a key role in undertaking the technical work to successfully restart the Mt Pass rare earth mine in the US, so in effect, Shenghe is the only group in recent years that has started a significant new rare earth project globally.
Greenland Minerals and Shenghe have worked collaboratively, and continue to do so, on optimising the processing for Kvanefjeld. This is ongoing and continues to bring about opportunities for performance improvements and greater project efficiencies. Ongoing optimisation is standard in the mining industry – Shenghe continue to optimise the Mt Pass operation that is now in operation.
Overall is would seem Professor Chahmouradian has not looked into the detailed and extensive geological, mineralogical and metallurgical studies and investigations into the Kvanefjeld Project.
Radioactivity of the lujavrites (Kvanefjeld ores)
Professor Chahmouradian states that there is nothing in the company’s spreadsheets about thorium. It is assumed that this reference is to the reporting of mineral resource estimates, the tables for which are commonly included in company announcements associated with technical or economic studies. When reporting mineral resources, only economic components of the ore are considered. It is not an area where all elements analysed are reported. Uranium is considered an economic component, whereas thorium is not (there is no market for thorium). Thorium, along with many other elements, is routinely assayed for, but is not an economic component, and is therefore not reported in resource tables. Clearly there is a lack of understanding on mineral resource reporting.
The thorium content of rocks and minerals at Kvanefjeld is very well understood. The management of thorium, and radioactivity in general is not dealt with in resource reporting, but in specific studies that relate to the project’s environmental impact assessment (this is where such matters should be reported and investigated). This includes detailed tailings management plans and associated studies. These studies are conducted by independent specialist consultancies. The studies have then been through a detailed review-revision process by the Greenland Government’s independent scientific advisors (see company announcement 23 September, 2020). The EIA for the project is available on the government website in three languages, with links to the detailed underlying technical reports. Clearly this has been completely overlooked. Draft versions of the EIA have been available for years on NGO websites amongst other portals.
Overall, the comments reflect a lack of understanding about many aspects of the Kvanefjeld Project, and therefore do not meaningfully contribute to discussions about the project. The Kvanefjeld Project has a number of unique attributes that underpin its strengths as a rare earth project. Notably, none of these were touched upon

Antwort auf Beitrag Nr.: 66.387.854 von heesi am 11.01.21 19:13:04Absolut richtig ausgeführt. Dieser Geologe und der armenische Journalist disqualifizieren sich gleich selbst. Sie haben weder denn technical EIA noch die EIA mit den dazugehörenden Berichten gelesen noch sich darüber schlau gemacht. Aber einfach mal so Grossmaul mässig ein Statement verfasst welches weder Hand noch Fuss hat.
Hinzu kommt, dass er vermutlich ein reiner Universitäts Theoretiker ist
https://umanitoba.ca/faculties/environment/departments/geo_s…
Und vor Ort war er schon gar nicht und mit den 15 weltweit zu den führendsten Experten hat er auch nicht gesprochen. Reine Polemikmacherei von einem russischen Geologen in Canada.
